Sodium Ascorbyl/Cholesteryl Phosphate, also known as L-Ascorbic acid, 2-[(3.beta.)-cholest-5-en-3-yl hydrogen phosphate], monosodium salt, is a unique cosmetic ingredient that combines the properties of Vitamin C (ascorbic acid) and cholesterol. This compound is primarily sourced from the synthesis of ascorbic acid and cholesterol derivatives, resulting in a molecule that offers both antioxidant and skin conditioning benefits.
The history of Sodium Ascorbyl/Cholesteryl Phosphate in cosmetics is relatively recent, emerging as a response to the need for more stable and effective forms of Vitamin C in skincare. Traditional Vitamin C, while highly beneficial, is notoriously unstable and can degrade quickly when exposed to light and air. By combining it with a cholesterol derivative, scientists were able to create a more stable compound that retains the potent antioxidant properties of Vitamin C while also benefiting from the skin-conditioning properties of cholesterol.
The production of Sodium Ascorbyl/Cholesteryl Phosphate involves a chemical reaction where ascorbic acid is esterified with a cholesterol phosphate. This process not only stabilizes the Vitamin C but also enhances its ability to penetrate the skin, making it more effective in delivering its benefits. The resulting compound is then neutralized with sodium to form the monosodium salt, which is more soluble and easier to incorporate into various cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Sodium Ascorbyl/Cholesteryl Phosphate:
Sodium Ascorbyl/Cholesteryl Phosphate acts as an antioxidant, which means it helps to protect your skin from the damaging effects of free radicals. Free radicals are unstable molecules that can cause oxidative stress, leading to premature aging, wrinkles, and other skin issues. By neutralizing these harmful molecules, this ingredient helps to maintain the skin’s youthful appearance and overall health.
Another key benefit of Sodium Ascorbyl/Cholesteryl Phosphate is its skin conditioning properties. This means it helps to improve the texture and feel of your skin. It works by enhancing the skin’s natural barrier, making it more resilient and better able to retain moisture. This can result in smoother, softer, and more hydrated skin, giving you a healthier and more radiant complexion.
Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
Sodium Ascorbyl/Cholesteryl Phosphate is generally considered safe for topical use in cosmetic products. However, as with any ingredient, there are potential side effects and considerations to keep in mind:
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of Sodium Ascorbyl/Cholesteryl Phosphate during pregnancy are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice.
Adverse reactions to this ingredient are relatively uncommon, but it is always prudent to conduct a patch test before widespread usage to ensure personal tolerance.
On a comedogenicity scale of 0 to 5, Sodium Ascorbyl/Cholesteryl Phosphate is generally considered to have a low comedogenic rating, typically around 1. This means it is unlikely to clog pores and cause acne or breakouts, making it suitable for individuals prone to blemishes.
